SPECIFICATION forming part of Letters Patent No. 656,321, dated August21, 1900. Application filed November 9,1899. Seria1No.736, 420. (Nomodel) To all whom if may concern:

Be it known that I, LUDWIG GROTE, manufacturer,a citizen of Germany,residing at 84 East India Dock road, London, in the county of Middlesex,England, have invented a new and useful Improvement in and Relating toWooden File an'd'other Tool Hafts or Handles with Paper-Cased ReedCores, of which the following is a specification.

The wooden file and other tool hafts or handles hitherto known areattended with the drawback that they are apt to split and crack whilethe tangs or shanks of the files or other tools are being driven intothem. Although metal ferrules have been employed to strengthen them, itwas necessary to previously drill or burn such handles in ordersatisfactorily to fit and secure the files or other tools in theirsockets. This involvedan expenditure of both time and money, which inmany cases proved unavailing, as the shank of the tool when fixed in itssocket was very frequently found to deviate from the straight line,while apart from this the wood by shrinking as it dried would cause themetal ferrules to slip off, and thereby render the tool-handleunserviceable.

The present invention obviates the drawbacks stated; and it consists inproviding each handle with a nucleus or core-piece inserted in itscenter and comprising a length of reed, ratan, bamboo, or the likeenveloped in a paper case, into which the shank or tang of the file orother tool may be forced without any fear of splitting or cracking thesurrounding wood. The ease and safety wherewith the tangs of files orthe like may be driven home into the improved handles or hafts areaccounted for by the yielding texture peculiar to reed, 850., which asit gives way to the pressure of the tang adheres withproportionately-increasing tightness to its outer paper casing, whichthus takes up the pressure that would otherwise be transmitted to thewood of the haft or handle and might lead to its disruption.

In the accompanying drawings, Figure 1 represents a piece or length-ofreed or the like retained by two centers in a windingmachine and readyto be wound with paper. Fig. 2 shows the length of reed provided withFig. 3 is a longitudinal the lathe.

section of a blank with a hole drilled into it and ready for turning ina lathe. Fig. 4: shows a file-haft after it has been turned in Fig. 5 isa cross-section of the upper end of the finished file-haft, illustratingthe manner in which the paper-cased reed core is fitted within thewooden socket. Fig. 6 is a longitudinal section of the paper-cased reedcore provided with a guiding-aperture for the insertion of thetool-shank. Fig. 7 shows the finished tool haft or handle, 011ehalf ofthe figure being a longitudinal section, showing the shank or tang of atool inserted into the paper-cased reed core and illustrating the mannerof securing the same in the handle or haft.

In producing the improved haft or handle I first fix the ratan-likereed, (ratan or the like,) hereinafter termed the reed, which haspreviously been cut to the required length in a winding-machine, bymeans of two centers. The reed is then wound with an endless strip ofpaper, which is fed along through a receptacle filled with a suitableadhesive substance, the winding being continned until the reedcorresponds in size to the aperture drilled in the wooden blank. (VideFigs. 2 and 3.) The wooden blanks, which have previously been drilled ina lathe or otherwise, as shown in the longitudinal section, Fig. 3, arenow turned in the lathe to the shape presented in Fig. 4. Thepaperwound' reed core is next covered with suitable adhesive materialand driven or forced into the aperture prepared for its reception in thehaft or handle blank, so that the corepiece and the wood surrounding itjointly form one compact body, as shown in the cross-section, Fig. 5.After the tool haft or handle so constructed has had time to dry theprotruding end of the paper-wound reed core is cut away and the toolhandle is mounted upon a tapering mandrel in the lathe to be planed,polished, 0r varnished, as may be desired. In consequence of the handlebeing driven upon the taper mandrel there will form within the same anaperture of conical shape adapted to receive and accurately guide thetool shank or tang subsequently to be inserted into the handle, Fig. 6.The yielding texture of the reed afiords the tool-shank ready access,while owing to its preferably turned or rounded off at the tool end inthe shape of a bead or head for the purpose of protecting it fromviolent contact with the article being operated upon at the time, theresulting concussion having heretofore been a frequent cause of toolsbecoming loose in their handles in a comparatively short time.

Having now described my invention, what I claim, and desire to secure byLetters Patent, is-

l. A wooden file or other tool haft or handle consisting of apaper-cased reed core-piece or nucleus surrounded by a wooden shelladapted to firmly retain in position the file or other tool shank ortang at both ends and to prevent its becoming loose in the reed, ratan,bamboo or the like of its own accord while at the same time protectingthe wooden shell or handle from cracking, splitting or warping.

'2. A tool haft or handle consisting of a paper-cased reed core-piece ornucleus, sur rounded by a wooden shell, and rounded ofi at the endwherein the extremity of the tang or shank of the tool is embedded, forthe purpose of affording better protection to that end of thehandle-core, and also for securing the tang from concussion and itsconsequent loosening through the violent'contact of the handle with thearticle operated upon at the time.

In witness whereof I have hereunto set my hand in the presence of twowitnesses.

LUDWIG GROTE.
